You'll be introduced to the best practices of maintaining your code clear and simple and how to avoid common pitfalls. We'll walk through building your authentication layer and adding your first entity.

You'll learn how to leverage JavaScript nonblocking architecture in building real-time communication between your server and client applications.

Finally, we'll show you how to cover your code with the proper tests and what tools to use to automate your development process. Skip to content. You may experience some trouble creating this folder. This is usually a permission issue, so use sudo or super user when running the preceding command. The preceding command will create the data and db folders, because the —p flag creates parent folders as well. Notice that the default folder is located outside your home folder, so make sure you set the folder permission by running the following command:.

Now that you have everything prepared, use your command-line tool and go to the bin folder to run the mongod service as follows:. This will run the main MongoDB service, which will start listening to the default port.

Sometimes, the easiest way to install MongoDB is using a package manager. The downside is that some package managers are falling behind in terms of supporting the latest version. Note that you'll have to configure your package manager repository to include the MongoDB servers to download the official packages. The MongoDB archive file includes the MongoDB shell, which allows to you to interact with your server instance using the command line.

To start the shell, navigate to the MongoDB bin folder and run the mongo service as follows:. If you successfully installed MongoDB, the shell will automatically connect to your local instance, using the test database.

You should see a console output similar to the following screenshot:. The preceding command will create a new article collection and insert a JSON object containing a title property. To retrieve the article object, execute the following command:. This means your MongoDB instance is working properly, and you have successfully managed to interact with it using the MongoDB shell. For the stable versions, the official Node.

Note that you need to download the right architecture version for your operating system. If you use Windows or Linux, make sure to download either the bit or bit version according to your system architecture. After the merge between the Node. The latest stable version of Node. Installing Node. Notice there are bit and bit versions, so make sure you download the right one for your system.

After downloading the installer, run it. If you get any security dialog boxes, just click on the Run button, and the installation wizard should start.

You will be prompted with an installation screen similar to the following screenshot:. Once you click on the Next button, the installation should begin. A few moments later, you'll see a confirmation screen similar to the following screenshot, telling you that Node. After downloading the installer, run it, and you will be prompted with an installation screen similar to the following screenshot:.

Click on Continue , and the installation process should begin. The installer will ask you to confirm the license agreement and then ask you to select the folder destination. Choose the option most suitable for you before clicking on the Continue button again. The installer will then ask you to confirm the installation information and ask you for your user password. To install Node. The best way of doing so is to download the latest version and then build and install the source code using the make command.

Then, expand the file and install Node. If everything goes well, the commands will install Node. Note that these commands are for the Node. It is recommended that you learn more about Node. After you have successfully installed Node. Go to your command-line tool and execute the following command:. This will start the Node.

To test the installation, run the following command:. This is nice, but you should also try to execute a JavaScript file. Start by creating a file named application. To run it, you'll have to pass the file name as the first argument to the Node CLI by issuing the following command:.

You have just created your first Node. To achieve more complex functionality, it uses a module system that allows you to extend the platform. The best way to install, update, and remove Node. Conveniently, npm is installed during the Node. To understand how npm works, we will install the Express web framework module, which you'll use in the upcoming chapters. Most of the packages in the registry are open source and contributed by the Node.

When developing an open source module, the package author can decide to publish it to the central registry, allowing other developers to download and use it in their projects. In the package configuration file, the author will choose a name that will later be used as a unique identifier to download that package.

It is important to remember that npm has two installation modes: local and global. It has no effect system-wise and is used to install the packages your application needs, without polluting your system with unnecessary global files. The global mode is used to install the packages you want Node. Usually, these are CLI tools, such as Grunt, that you'll learn about in the upcoming chapters.

Most of the time, the package author will specifically instruct you to install the package globally. Therefore, whenever in doubt, use the local mode. Once you find the right package, you'll be able to install it using the npm install command, as follows:. Installing a module globally is similar to its local counterpart, but you'll have to add the —g flag, as follows:.

You may find out that your user doesn't have the right permissions to install packages globally, so you'll have to use the root user or install it using sudo. For example, to locally install Express, you'll need to navigate to your application folder and issue the following command:. Furthermore, npm supports a wide range of semantic versioning.

So, to install a specific version of a package, you can use the npm install command, as follows:. For instance, to install the second major version of the Express package, you'll need to issue the following command:. This will install the latest stable version of Express 2.

Note that this syntax enables npm to download and install any minor version of Express 2. To remove an installed package, you'll have to navigate to your application folder and run the following command:.

To remove a global package, you'll need to use the -g flag, as follows:. To update a package to its latest version, issue the following command:. To update a global package, use the following command:. Installing a single package is nice, but pretty soon, your application will need to use several packages. So, you'll need a better way to manage these dependencies.

Revisions to the overall layout, including several new section types that better guide the reader with advice. Some changes to the page layout to help readers distinguish advanced topics from more introductory material, allowing students to focus at a level appropriate for their learning.
